1 answer:

5 0

9 represents the event, 13 represents all possible events.

I have a bag of 13 marbles. 9 of my marbles are blue, 4 are red. My probability of reaching in and pulling out a blue marble at random is 9/13 (Which is 69%)

Answer:

the triangle above is an isoceles triangle

therefore the base angles are equal

So we have:

X + X + 38= 180

2x = 180-38

2x = 142

X = 71°

Answer:

17662.5 sq. feet

Step-by-step explanation:

We know that the formula for Area of a Circle is $A = \pi (r)^2$ .

r = radius; d = diameter, which is r*2

And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.

150/2 = 75

The question said to keep $\pi$ =3.14, so then we plug in the equation-

$A = 3.14 * 75^2$

Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-

$A = 3.14 * 5625$ (first doing the Exponent)

And we continue-

$A = 17662.5$ (then multiple)

So our answer is-

17662.5 sq. feet

I hope this helps!
Please give brainliest!

Have a great day
